MACHINE FOR MAKING BUTTON-HOLE Lmmes.

SPECIFICATION forming part of Letters latent No. 282,078, dated July 31,1883.

Application filed December 52, 1882. (No model.)

To all whomrit may concern.-

Be it known that I, DAVID HARRIS, a citizen of the United States,residing at Brooklyn, in the county of Kings and State of New York 5have invented certain new and useful Improvements in Machines for MakingButton- Hole Linings, of which the following is a specification,reference being had therein to the accompanying drawings. g

The object of this invention is to strike up or punch a bead or embossedsurface upon a piece of leather, and at the same time condense a portionof the leather which forms the bead, and thereby render the bead moredense and firm, and therefore stronger,'than the mate rial was beforesuch operation, whereby I am enabled to produce a button-hole lining ofgreat strength, and which is specially adapted to support the strain orpull of buttons, particularly upon shoes and similar articles.

The invention consists in certain novel features of construction andoperation, as will be hereinafter fully explained.

Figure l is a perspective view of a machine constructed in accordancewith my invention. Fig. 2 is a plan view of the same. Fig. 3 is a sideview, the bed-plate being in section. Fig. 4 is a view partly in sectionon line 3/ y, Fig. 2. Fig. 5 is a vertical section, enlarged, of the 30embossing and cutting mechanism, taken 011 the same section-line. Fig. 6is a bottom view of the die. Fig. 7 is a detached view, enlarged, of thematrix and cutter; and Fig. 8 is a vertical section 011 line m, Fig. 7

Similar letters of reference indicate corresponding parts in all thefigures.

In the drawings, A a is a table, the part a being shown as elevated uponthe part A for convenience in pivoting some of the mechanism thereto;but such construction is not indispensable.

B is a foot-treadle, pivoted below the bedplate and within convenientreach of the op erator when sitting in front of the machine.

b is a link pivoted at its lower end to the treadle and adjustablyattached at its upper end to lever O, which is mounted upon and pivotedto the upper end of vibrating bars 0 c. I

D is a die-carrier reciprocating inthe end d of a support-standard.

I will now describe the die, matrix, and punching and cutting mechanism,referring more particularly to Figs. 4, 5, 6, 7, and 8..

E F is a die composed of two members, the shank e of the upper memberbeing mounted in and carried by the die-stock D. (See Fig. 4.) Forconvenience of manufacture and repair, I 7 construct this die in twoparts, the lower member, F, being attached to the upper member, E, bysuitable screws, f f, or otherwise. The lower member or plate isprovided upon its working-face with an embossing rib or bead, G, thecircular portion of which surrounds a circular eye, H, its legsextending upon opposite sides of a slit or throat in said plate to suchlength as maybe required.

9 g are guide pins or studs projecting downwardly from the die, andadapted to enter holes 2' t in the upper face of the matrix I. (See Fig.7.) The matrix is provided upon its upper face with a recess, J,corresponding in form to the embossing rib or bead G, and with a slit oropening in the center of the straight portion of the recess, which slitcommunicates with a round hole in the center of the circular part of therecess. (See Figs. 5 and 7.) I sometimes make this matrix in two piecesof substantially the same area and thickness, as indicated in Fig. 5.This matrix is mounted upon a swinging carrier, L M, pivoted to thebed-plate N by a stud or screw, m, (see Figs. 7

and 8,) and is connected with the part L by means of four studs, Z Z,upon which it is free to rise and fall when actuated, and for a purposewhich will be hereinafter fully explained.

g y are semi-elliptical springs interposed between the part L of thecarrier and the ma triX I.

K is a punch carried by the part L, and having its upper end supportedin a round hole in the matrix.

It is a knife, also carried by the part L, and having its upper endsupported in a slit, which is central in the straight portion of therecess in the matrix, and which has been heretofore referred to. (SeeFigs. 5, 7, and 8.)

h is a throat in the part E of the die, communicating at its lower endwith the opening H within bead' G.

I will now describe. the mechanism for m0vtoo ing the matrix to aposition underneath the die and removing it therefrom. Referring toFigs. 1, 2, 3, O is a link or draw-bar, pivoted at one end to the freeend of the part M of the matrix-carrier and at its opposite end to theend P of a horizontal lever,whieh is pivoted at 1 to the bedplate N. Theopposite end, 1), of this lever projects rearwardly from the bedplateand into the path of the end Q of a vertical bell crank lever, which ispivoted at 2 to the table A, and has its end q connected by a link, It,with the lever c. The position and relation of these levers and linksare shown particularly in Fig. l, the lower part of the bellcrank leverand its pivot being in dottedlines. S is a spiral spring, connected atone end to link 0 and at its opposite end to bed-plate N. sis a stopprojecting from bed-plate N to engage with link a: (see Figs. 1, 2, and4) is a stop to engage with the rear end of the matrix and insure thatit shall be stopped in proper position to receive the die.

By an examination of the drawings it will be readily seen that when thefront end of the treadlc is depressed and the rear end of the lever C israised the link R, connected upon the bell-crank lever Q q, will causethe end Q of such lever to engage with the end of lever P p, and thuspulling upon link 0 will swing the matrix from the position shown inFigs. 1 and 3 into position shown in Figs. 2 and 4. Then the treadle isreleased the rear end of the lever 0 falls, thus returning the end Q ofthe bell-crank lever to the position shown in Fig. 1, and the spring Sreturns lever Pp,

. link 0, the matrix, and its carrier to the position shown in Fig. -1.

T is an adjustable matrix-support, consist ing, essentially, of ahorizontal face-plate perforated centrally and having adownwardlyprojecting horizontal flange. It is located in an opening inthe bed-plate, where it is adjusted and held firmly in proper positionby means of three set-screws, t if, and in proper position to supportthe matrix and its carrier firmly against downward thrust. U is ahorizontal link, pivoted at one end to the end Q of the bell-cranklever, its opposite end being slotted, as at a, and connected by meansof a largeheaded stud or bolt to one end, V, of a lever, which is.pivoted at 3 to the elevated portion a of the table. The front end, 2),of this lever is beveled.

IV is a lever pivoted at at to the table, and carries at it front end astripper, X, provided with one or more downwardlyturned spurs.

w w are springs attached to the inner shorter end of lever IV, one ofthese springs being also attached at one end to lever Vv, these springsserving to hold these levers in the position indicated in Fig. 1 and infull lines, Fig. 2. The vertical distance between the upper and lowerpoints of the stripper X is about equal to the distance between thehorizontal planes of the upper face of the matrix and the lower face ofthe die when the die is at about its highest point.

In Fig. 4 I have shown the die-stock D, hav ing upon its front face akeyseat or groove, in which is fitted a key adjusted by set-screws, as iscustomary in various presses, and need not therefore be specificallydescribed.

Z is a gas-pipe, the tip or burner of which is arranged in closeproximity to the hollow under surface of the matrix-support to supplyheat, which I employ for the purpose of as sisting in the production ofasuitable head, the hole in the horizontal face-plate of this supportfacilitating the passage of the heat to the matrix and die.

2 is a stop-cock in the gas-pipe.

The machine may be operated as follows Supposing all of its parts to bein a position indicated in Fig. 1, the operator makes a suitable blankby cutting a piece of leather into oblong or oval shape, and of suchsize as will lie upon the matrix Ibetween theheads of setscrews Z Z andthe holes 1' 13, (see Fig. 7,) the blank being in suitable temper. Theoperator then depresses the treadle, raising the rear end of lever G,which operation not only depresses the die and die-stock, but also, bymeans of levers P Q and link 0, swings the matrix upon the set-screw m,carrying the matrix and blank into proper position under the die, when acontinued movement of the treadle in the same direction presses the diedown upon the blank and thrusts a portion of the leather into the recessJ J, thus raising the desired bead. This movement also thrusts thematrix down upon the part I of the matrix-carrier un til the punch K andknife k cut the slit in the leather, and the punch is thrust through thesmall hole in the blank, thus further compressing the leather into thecircular portion of the recess and materially increasing the density andfirmness of the bead around the eye of the button. lVhile this movementof parts has been effected the link II has been thrust in the directionindicated by the arrow 5, swinging the lever V '0 upon itspivot untilthe end 1; has been thrust past the inner end of lever W. \Vhen theparts are being returned to the position shown in Fig. 1, the link U,moving in an opposite direction, moves the levers V o W first into theposition indicated in dotted lines, Fig. 2, whereby the stripper X iscaused to traverse both the upper face of the matrix and the lower faceof the die, thus stripping the button-hole lining from either the matrixor the die incase it adheres to either of them. Just before the link 1)reaches the limit of its downward travel the end 12 of the lever escapesfrom the inner end of lever \V and permits springs 10 to return thatlever and thestripper to the position shown in Fig. 2.

Although I have shown in the drawings a machine which I have devised andoperated for the carrying out of my invention, I do not wish to belimited to the precise construction or arrangement of parts shown, asmany 1nodifications might be made therein without departing from thespirit of my invention. Nor

do I wish to be limited to the use of a movable matrix, because thematrix might be made stationary and the die so constructed as to bealternately moved over the matrix and away from it. Nor do I wish to belimited to making the matrix movable for the purpose of thrusting thebutton-lining down against the punch K or the knife 70, as mechanismmight be employed to thrust said punch and the knife upwardly throughthe matrix.

I do not claim in this case any of the inventions herein described andshown, except those specifically set forth in the claims, preferring toclaim all other patentable inventions herein shown in anotherapplication which I am about to file as a division of this case.

What I claim is- 1. In a machine for making button-hole linings, thecombination, with a matrix provided with a circular opening adapted toreceive a punch, a slit adapted to receive a knife, and a recesssurrounding the opening and the slit, of a movable die provided with abead corresponding to the recess, substantially as set forth.

2. In a machine for making button-hole linings, the combination of amovable matrix provided with a recess, substantially of the form-shownat J, and die provided with a correspondingly-shaped rib, as at G, themeans for moving the matrix under the die, and means for depressing thedie, substantially as 5 set forth.

3. In a machine for making button-hole linings, the combination of a dieand matrix adapted to form a bead, substantially as set forth, and amovable stripper adapted to remove the button-hole lining, substantiallyas set forth.

4. Ina machine for making button-hole linings, the combination, with thedie, of a matrix adapted to be moved into the path of the die and to bewithdrawn therefrom, and a knife adapted to cut a buttonslit,substantially ings, the combination of the die, the matrix,

and the matrix-support, substantially as set forth.

8. In a machine for making button-hole linings, the combination of thedie, the matrix, and the matrix-support, provided upon its under sidewith a recess adapted to be heated by gas, substantially as set forth.

In testimony whereof I affix my signature in presence of two witnesses.
